had been, as to component members, he could by exercising his peremptory challenges, which he did not exhaust, have thus rid himself of those to whom he objected. Sawyer v. United States, 202 U. S. 150, 26 S. Ct. 575, 50 L. Ed. 972, 6 Ann. Cas. 269;
Connecticut Mutual Life Ins. Co. v. Hillmon, 188 U. S. 208, 23 S. Ct. 294, 47 L. Ed. 446; Krause v. United States (C. C. A.) 147 F. 442; Simpson v. United States (C. C. A.) 184 F. 817; Richards v. United States (C. C. A.) 175 F. 911; United Mine Workers v. Coronado Coal Co. (C. C. A.) 258 F. 829; Tierney v. United States
(C. C. A.) 280 F. 322. It is persuasive, though not controlling, that the rule in Arkansas seems in accord. Rose v. State, 178 Ark. 980, 13 S.W.(2d) 25.
So, we think the error urged must be disallowed, upon the grounds indicated, first, that appellant waived it, by failing to raise it, when it first occurred, and, second, because he had no vested right to have any particular juror on the trial panel; since, a fair and impartial panel being conceded, his sole right was that of rejection, which, his challenges not having been exhausted, was still open to him before the jury was sworn.
The point made that the charge of the court should have required the jury to find, before they could convict appellant, that the latter knew, at the time he assaulted the witness, that an indictment had been found against appellant and was at such time actually pending, is urged by appellant with much insistence.
While the statute nowhere expressly mentions the necessity for such knowledge, or any knowledge, it is yet by its terms such a statute as requires knowledge on defendant’s part to be charged in the indictment, touching the fact that the person assaulted is a witness in a pending case, and so the courts have held. Genna v. United States (C. C. A.) 293 F. 387; Pettibone v. United States, 148 U. S. 197, 13 S. Ct. 542, 546, 37 L. Ed. 419. But we have found no case which requires the jury to find the existence of actual knowledge by a defendant of such fact as contradistinguished from “reasonable grounds to believe,” as in effect, the trial court charged.
In the Pettibone Case, supra, the court said, on the point of the necessity that the accused should have knowledge of the pend-ency of proceedings ip court, this: “The construction that applies to the first branch of section 5399 must be applied to the second, and if it were essential that the person accused should know that the witness or officer was a witness or officer, in order to conviction of the charge of influencing, intimidating, or impeding such witness or officer in the discharge of his duty, so it must be necessary for the accused to have knowledge or notice or information of the pendency of proceedings in the United States court, or the progress of the administration of justice therein, before he can be found guilty of obstructing or impending, or endeavoring to obstruct or impede, the same.”
Clearly, the Supreme Court held in mind that notice was all that was required, and notice is not so strong a requirement as knowledge. No case which we have been able to find, or which has been unearthed by the diligence of counsel, sets out categorically the quantum of proof requisite to show either knowledge or notice.
The point does not occur to us as being wholly analogous to the knowledge required to be proved in a charge of transporting a stolen automobile in interstate commerce; for the reason that in the latter case, knowledge of the fact of recent theft of the automobile is the very gist of the offense, while in the case at bar it is the intimidation of the witness, which constitutes the prime constituent of the offense. Concededly, the person criminally dealt with must be a witness [Smith v. United States (C. C. A.) 274 F. 351], at the time of the intimidation; and the intimidation must be because of such status, but to require proof that a defendant had actual knowledge, for example that an indictment had been found against him and was pending, would in many cases render enforcement' of the statute an impossibility. The statute is necessary, and day by day becoming more so, and we- do not think it should be emasculated, if not wholly destroyed, by requiring a degree of proof wellnigh impossible. If the accused has reasonable grounds for belief that a case is pending and that one, whom he deals with in the teeth of the statute, is or is going to be a witness in such case, and then uses force to intimidate such witness in an effort, and with the intent to affect such witness’ testimony, that should be all that is necessary. So, conceding that one should not be convicted, unless when acting he knew the person dealt with is, or is going to be a witness in a pending case, we think the matter of required knowledge may be shown by proof of reasonable grounds for such knowledge. Of course, such grounds-
